Not sure this is doable in one turn, but I hope we can. Sam should be able to carry 80Kg and i doubt fractal is over average, i recall him being smaller then average.
Sam takes Fractal(3) and starts running out of the Room where he had just set the Charges
Lifting and Carrying (STR + BOD )
A character can lift off the ground 15 kilograms per point of Strength without making a test. If the character wishes to lift more than that, she may make a Strength + Body Test. Each net hit increases the weight she can lift by 15 kilograms more.
A character can lift 5 kilograms per point Strength over her head without making a test. If the character wishes to lift more than that over her head, she may make a Strength + Body Test. Each net hit increases the weight she can lift by 5 kilograms more. Characters can lift and carry their Strength x 10 kilograms in weight without any sort of test. Lifting and carrying more than that calls for a Strength + Body Test. Each hit increases the weight she can lift by 10 kilograms more. For more details on carrying gear, see Carrying Gear, p. 310.
He is lighter than most elves, something on his 70kg or even a little less, on my imagination.
Still my action if it is possible, is to carry Fractal out of the Danger zone of the Explosion, 15 m should get us out of the second room, and if there are no secondary explosions this room should still be intact. not so sure about the living room and the laboratory. at least halfway they should be destroyed and collapsed.
Even thou he could geek the mage, or at least hurt him a bit more, everything he knows from the old horo-flics point toward life stealing zombies and blood magic using sacrifices to stay alive even when fatally wounded, so better getting away from here while they still can trap him down here.
